A container system comprising two identical interlocked vessels, each of the two vessels defining a separately sealed volume,

• each of the two vessels comprising a pair of generally triangular side walls, the pair of generally triangular side walls being generally parallel to each other, the pair of generally triangular side walls being joined together by a first generally vertical end wall and a second generally vertical end wall, the first generally vertical end wall being longer than the second generally vertical end wall, the second generally vertical end wall defining a vertically extending recess, the vertically extending recess having a shape of a partial cylinder, the pair of generally triangular side walls being connected by an interconnecting wall, the interconnecting wall comprising a first portion and a second portion that are connected by a handle portion, the interconnecting wall defining an upper wall and a lower wall of the container system when the two identical interlocked vessels are secured together, an outlet defined at a base of the first generally vertical end wall, the outlet extending downwardly and outwardly relative to the interconnecting wall such that, when the two identical interlocked vessels are connected, the outlet is positioned above the vertically extending recess at a non-parallel angle, a parting plane extending at a non-ninety degree angle relative to the interconnecting wall and defining a plane along which the two identical interlocked vessels connect, and the outlet having at least a portion that is intersected by the parting plane when the outlet is in a closed position.

A container system comprising a plurality of vessels that are connectable together:

• one of the plurality of the vessels being an upper vessel and one of the plurality of vessels being a lower vessel;
• each of the vessels defining a separately sealed volume, each of the vessels comprising a pair of parallel side walls and an outlet positioned between planes defined by the pair of parallel side walls, the pair of parallel side walls being connected by a plurality of peripheral walls, a short peripheral wall being positioned to a first end of the pair of parallel side walls and a long peripheral wall being positioned to a second end of the pair of parallel side walls, the short peripheral wall defining a vertically extending recess, the vertically extending recess having a shape of a partial cylinder, an interconnecting wall connecting the short peripheral wall to the long peripheral wall, the interconnecting wall comprising a first portion and a second portion that are connected by a handle portion, the interconnecting wall defining an upper wall and a lower wall of the container system when the two identical interlocked vessels are secured together, the outlet being adjacent to the long peripheral wall;
• the outlet of the upper vessel being the lowermost portion of the upper vessel, and the outlet of the lower vessel being the uppermost portion of the lower vessel, the outlet of the upper vessel projecting further laterally outward relative to the adjacent side wall of the lower vessel with the upper vessel mounted on the lower vessel, and the uppermost portion of the upper vessel being positioned higher than the uppermost portion of the lower vessel.
